Analyze Building for HVAC Requirements

There are two workflows that demonstrate how to calculate energy requirements for maintaining the building at your desired set point temperature. One workflow, the livescript, describes a short, hourly, 1 week analysis. The other workflow describes analysis for a house constructed at multiple locations and over a period of one full year. The requirement or the heat load analysis uses the BuildingModelWithSolarLoad model for analysis (Models/BuildingModelWithSolarLoad.slx).
Average Requirements for Different Seasons and Location
In the workflow Building Heat Load Estimation (Workflow/BuildingHeatLoadEstimation.mlx), you use a building model, created earlier, and compare the heat load for similar building in different geographical locations. You will evaluate the impact on energy consumption from operational parameters linked to time of the day, such as number of occupants at a given day and time, additional electrical loads, and switching on/off the HVAC system. To open and run the workflow, enter at the MATLAB command prompt.

Hourly Requirements over Week for a Location
In the workflow Building Management System Requirement Analysis (Workflow/BuildingManagementSystemRequirementAnalysis.mlx), you calculate energy requirements for maintaining the building rooms at the desired set point temperature.
In both these workflows, there is no heat pump, room radiator, underfloor heating / cooling. The Controls subsystem calculates the energy required to keep the building at the set point temperature based on the solar load and changes in ambient temperature. The BuildingModelWithSolarLoad model runs at fixed hourly-timestep. To open and run the workflow, enter at the MATLAB command prompt.
